San Bernardino Title 24 Climate Zone 10
San Bernardino is in Climate Zone 10. The city's inland valley location means summer temperatures regularly exceed 100 degrees. Zone 10 requires demanding insulation values, efficient HVAC systems, and solar PV for all new construction. The heat trapped by the surrounding mountain ranges makes San Bernardino one of the hotter locations within Zone 10. As a result, duct leakage and HVAC sizing are especially important for residential projects here.
Confirm the current code cycle with the Building and Safety Division at (909) 384-5071 before ordering your report. For inspections, contact SB Direct at (909) 998-2000. We confirm which code applies to your specific project when you submit your plans.
We confirm your exact climate zone by project address before starting any report. The California Energy Commission climate zone tool provides the official zone map. You can also view our full California Title 24 climate zones guide for zone-by-zone details.

CF1R Reports and HERS Testing in San Bernardino
The Building and Safety Division requires a CF1R Certificate of Compliance for all residential permits that trigger Title 24. Title 24 Calcs prepares the CF1R using current CEC-approved software. The software uses the 2025 code. We register it with an approved HERS provider before delivery. As a result, it is ready for permit submittal.
| CF1RCertificate of Compliance — submitted with the San Bernardino permit application | CF2RCertificate of Installation — signed by the installing contractor in the field | CF3RCertificate of Verification — signed by a HERS Rater before San Bernardino final inspection |
HERS testing is mandatory for specific energy systems. A certified HERS Rater must verify duct leakage, heat pump refrigerant charge, ventilation flow rates, and battery readiness. The city requires this verification before issuing a certificate of occupancy. Your CF1R identifies all applicable HERS measures for your San Bernardino project.
